Gintani C63 AMG M156 V8 Header Back Exhaust Development + Dynos

Gintani is wrapping up development of their C63 AMG exhaust. After the final round of testing the car was flashed back to stock and here we have a dyno of the car from the baseline stock to with the exhaust and tune. Stock the car put down 360 whp and with the exhaust alone on 91 octane the car put out 402.0 whp. A very, very nice gain with exhaust alone. Expect pricing information to come shortly.
